Instead of running the preparation tool separately, Microsoft offered an offline ISO named VS2012.5.iso. This ISO includes the preparation logic within its redist folder. If you mount the ISO and run vs_ultimate.exe (or your edition), the preparation step is automatically invoked. Only download the standalone visual studio 2012 update 5 preparation.exe if you already have the ISO mounted and the installer fails.
